Natural organic matter removal by coagulation during drinking water treatment: A review
TLDR
Most of the NOM can be removed by coagulation, although, the hydrophobic fraction and high molar mass compounds of NOM are removed more efficiently than hydrophilic fraction and the low molarmass compounds.About:

Effect of ion exchange dialysis process variables on aluminium permeation using response surface methodology
TL;DR: In this article, the authors investigated aluminum permeation using a counter flow ion exchange dialysis (IED) system and the optimum conditions for permeation were investigated using response surface methodology (RSM) using four factors-feed concentration (100-2,000 ppm, A), feed flow rate (25-85%, B), sweep concentration (0.25-1 N HCl, C) and sweep flow ratio (25 −85%, D) were studied using face centered central composite (FC-CCD) statistical experimental design.

Dense membranes precoated with aluminium tridecamer (Al13) for water treatment
TL;DR: In this article, an in-situ surface modification technique was applied by directly depositing the laboratory synthesized coagulant, aluminium tridecamer ([AlO4Al12(OH)24(H2O)12]Cl7, Al13), as a coating solution for two nanofiltration and one reverse osmosis (RO) membranes.

Photodegradation of humic acid in aqueous solution using a TiO2-carbonaceous hyper-cross-linked polystyrene polymer nanocomposite
TL;DR: In this article, the photodegradation of humic acid using a composite photocatalyst made up of TiO2 nanoparticles and a carbonaceous hyper-cross-linked polystyrene-type precursor derived from post-consumer waste poly styrene was reported.
Journal ArticleDOI
The interaction between effluent organic matter fractions and Al2(SO4)3 identified by fluorescence parallel factor analysis and FT-IR spectroscopy
TL;DR: In this article, the coagulation performance of EfOM fractions with Al2(SO4)3 was investigated in terms of turbidity reduction and dissolved organic carbon (DOC) removal.

Coagulation by hydrolysing metal salts
Jinming Duan,John Gregory +1 more
TL;DR: In this paper, a detailed understanding of the sweep flocculation mechanism is provided, especially with regard to the role of charge neutralization and hydroxide precipitation. But the results can be reasonably well explained in terms of established ideas, and there are also some uncertainties regarding the action of pre-hydrolysed coagulants.
